VISUALIZATION SYSTEM FOR VISUALIZING AN ALIGNMENT ACCURACY
The invention relates to a visualization system (10) for visualizing an accuracy of an alignment of a position and shape of an instrument (33), which has been determined by a position and shape determination device (9), with an image of the instrument. The accuracy is determined for different regions of the instrument as defined by the position and shape and of the image, wherein among these regions at least one region is determined, in which the determined accuracy indicates that it is insufficient. A visualization is then generated in which the determined region is indicated on a representation of the position and shape and/or the image. This visualization guides a user's eyes to the region which should not be missed, while deciding whether, for instance, a navigation of the instrument during a subsequent interventional procedure should be based on this alignment, which in turn allows for an improved navigation accuracy.
Cone beam computed tomography image acquisition protocols typically acquire a series of 2D projection images around a region of interest of a patient. The time required for a C-arm to travel around an acquisition orbit around the region of interest of a patient is non-trivial, and as a result, a patient being imaged may move during the acquisition. This is problematic because many computed tomography image acquisition algorithms assume that a patient is perfectly still during the acquisition time. If patient moves as the series of 2D projection images is being obtained, a 3D reconstruction will be affected by image artefacts. This application proposes to identify and to remove image artefacts caused by the relative motion of at least two rigid objects in the region of interest (For example, a mandible moving with respect to a skull during the acquisition). The at least two rigid objects have a more predictable motion characteristic, which may be used to correct 2D images of the input projection image sequence before a final reconstruction step. Accordingly, 3D images of a patient may be provided with fewer artefacts even when a patient moves during an acquisition.

The set of instructions when exectured by the processor further cause the processor to determine an erroneous code in the medical report, based on the vector representations.
